Introduction: T,G,B,F Robot. How to Build Our Awesome Robot

The purpose of building this robot is to see how much weight our robot can pull within the least amount of time with our own design. We as a team decided to use (4)100 MM wheels because we believed that using larger wheels are better for support and creates an increase amount of speed. As well we decided to use 3 gears for both sides, (2) 60 tooth gears(one in the back on the side of the robot, and one in the on the side of the middle), and (1) 36 tooth gear (in the front on the side of the robot). We believe our design is capable of holding more weight, due to the fact that we incorporated more then 2 gears and using 4 wheels (2 on each side.)

Step 1: Materials

Materials for Sled:

(1) Plate (5) Bearing blocks

(10) 0.318" ( 8.1 mm ) Plastic spacers

(10) 8-32 BHCS x 3/4" ( 19.1 mm )

(10) Keps nuts

attaching the hitch

(1) 5-hole angle bar

(2) 0.182" ( 4.6 mm ) Plastic spacers

(2) 8-32 BHCS x 1/2" ( 12.7 mm )

(1) 8-32 BHCS x 1/4" ( 6.4 mm )

(3) Keps nuts

(1) 8-32 BHCS x 3/4" (19.1mm)

- Materials for Robot:

-36 tooth gears (2)

-60 tooth gears (4)

-Vex Controller (1)

-Motor (2)

-100MM wheels (4)

-Long Bar (1)

-Medium Bar (2)

-Short Bar (2)

-Large Spacer (6)

-Collars (10)

-8/32 1/2'' screws (28)

-8/32 1/4'' Screws (4)

-8/32 3/4" screws (4)

-Keps Nut (32)

-Chassis Rails (4)

-15-hole angle bar (1)

-Chassis Bumper (1)

-Small spacers (24)

-Battery (1)

-Flat Bearings (12)

-Hex Wrenches (2) skinny and fat

(Tape for battery (1) to keep the battery in place if needed.)

Step 2: Building the Chassis Construction

1. To make the chassis frame we are going to use 2 Chassis Bar, 8/32 x 1/4'' screws (4), 15-hole angle bar,chassis bumper(1), And Keps Nuts (4)-you are going to align the 2 chassis bar with the 15 hole angle bar

-Align the holes in the fourth slotted hole from the end of the angle bar.

-Tight screws with keps nuts behind the screw, use hex wrench for help to tighten if needed.

2. Assembling the chassis bumper

-Align the 2 chassis bar with the chassis bumper on the fourth hole from the end of the chassis bumper.

Step 10: Add Battery to Vex Controller

2. Plug the battery into the the Vex controller that is attached to the top of your robot

3. Also to connect the two motors place the red and black plug from the motors into the available number 1 and 10 slots in the controller.

*your robot should be moving forward, by placing the motor cords in the right slots this creates the direction of your robot.

Step 11: Final Product, Checking for Errors, and Running the Robot

The robot should look exactly like the one in the photo. To check for errors run the robot to make sure that it's moving correctly and in the right direction. If the robot doesn't run this means you didn't follow the previous steps correctly.
